Abstract (en)
[origin: WO9606506A1] For bidirectional motion-compensated interpolation in the decoding of compressed video sequences, the invention proposes that only one of the two reference images is completely decoded. From the other reference image, only those areas of the image are decoded which overlap with the area being processed of the interpolated image, allowing for the displacement related to motion compensation.
